［摘要］貴陽漁安·安井溫泉旅游城“未來方舟”B6組團(tuán)環(huán)形車道邊坡最大擋土高度為28m，支護(hù)結(jié)構(gòu)采用拱形鋼筋混凝土連續(xù)墻支護(hù)方案。支護(hù)結(jié)構(gòu)充分利用逆作拱墻的空間受力特點(diǎn)，平面上土壓力主要通過軸壓力方式沿著拱軸方向傳至兩端先行施工的人工挖孔支護(hù)樁區(qū)段，支護(hù)結(jié)構(gòu)效率較高。采用規(guī)范計(jì)算公式及施工模擬分析，對邊坡的穩(wěn)定性及受力進(jìn)行計(jì)算分析。工程竣工后的位移監(jiān)測結(jié)果表明，邊坡支護(hù)結(jié)構(gòu)變形滿足設(shè)計(jì)要求。

Abstract:The maximum retaining height of the slope of the circular ramp is 28m in the “Future Ark” B6 group of Yuan·Anjing hot spring tourist city in Guiyang. An arched reinforced concrete continuous wall system was adopted for the supporting structure. The supporting structure makes full use of the spatial mechanical characteristics of the top-down constructed arched wall. The earth pressure is mainly transmitted through the axial direction of the arch to the artificially excavated supporting pile sections that are constructed in advance at both ends, and the supporting structure has high efficiency. The standard calculation formula and construction simulation analysis were used to calculate and analyze the stability and stress of the slope. The displacement monitoring results after the completion of the project show that the deformation of the slope support structure meets the design requirements.
Keywords:slope supporting; top-down constructed arched wall; slope stability; construction simulation analysis； displacement monitoring
